Let's divide 279398 by 81
We're looking to find how many times 81 goes into 279398.

Going ahead to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 81

Advancing to step 2:
If we divide 27 by 81, we get 0 and a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 81

On to step 3:
When dividing 279 by 81, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 243 from 279 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 81

Advancing to step 4:
81 can be fit into 363 4 times, resulting in a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 324 from 363, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 81

On to step 5:
399 divided by 81 is 4 with a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 344.0
If we take 324 away from 399, we end up with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 81

Advancing to step 6:
When dividing 758 by 81, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 3449.0
Subtracting 729 from 758 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
81 can be fit into 290 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 3449.3
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3449.35
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
81 goes into 650 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 3449.358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 81 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3449.358
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 81 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 3449.35802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
When dividing 380 by 81, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 3449.358024
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
81 goes into 560 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 3449.3580246
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
81 goes into 740 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 3449.35802469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 3449.35802469, and the remainder is 1.1e-08.
